In three years, the Delinquency Study and Youth Development Project of Southern Illinois University has provided for five students to do their student teaching incorrectional settings. From this experience, it has been found that student teachers bring new educational ideas into the institution; student teachers function well when viewed as potential staff members; student teachers stimulate good public relations inasmuch as they tell others about the work of the institution; although student teachers may increase management and security problems, they also make evident the need for change and institutional development; the institutional superintendent must devote some time to the student teaching program, particularly in consulting with the university supervisor; and complete and honest communication between the university and the correctional institution is essential.
